Changing ISPConfig - FTP

Hi,
Would it be possible to make it if you tick the ftp access box for the site that the user that owns the site has an ftp account set up with there username and password for thats site. Instead of having to create a user & email for the site to have ftp access.
Thanks,
Alex

Would it be possible to make an FTP accounts tab under a site, and there you can create FTP users, becuase you may not want someone with an email account to have FTP access or the other way arround you might not want an FTP user to have an email account,
Thanks,
Alex

, I have got a new idea would it be possible to make an extra tab "FTP ACCOUNTS" on the "ISP site" form via the form designer, which has username & password for the ftp account and then when it saves it adds the user to proftpd. Then remove ftp access from the users with email accounts somehow.
Any idea how i could do this?
Thanks,
Alex
